Abstract

The utility model provides a foamed granular feeding device, in order to prevent foam granules blocked in the outlet of the hopper or strand feeding, the utility model comprises a hopper and a conveying pipeline connecting the outlet of the hopper as well as the blower. A rotor is arranged between the outlet of the hopper and the conveying pipeline, with at least three feeding leaves on the circumferential lateral wall, and the rotor is connected with the power output vertically on one end. The foamed granules can feed into the conveying pipeline quantitatively through the feeding leaves by arranging a rotor with feeding leaves at the outlet of the hopper and a brush on the end of the leaves. The brush can not only remove the residues of a small amount of granules, but also prevent the air in the conveying pipeline releasing from the outlet of the hopper, resulting in the establishment of certain pressure in the conveying pipeline to prevent the blockage of materials, and thereby guaranteeing the compactness of foamed molding products uniform and stable.

Description

A kind of foam beads charging gear

Technical field

The utility model relates to a kind of foamed plastics making apparatus, relates in particular to a kind of foam beads charging gear.

Background technology

Known foamed plastics making apparatus generally comprises hopper, conveying pipeline, air blast, die cavity, heating pressue device etc.The Chinese patent CN1298339A that announces June 6 calendar year 2001 discloses a kind of interior foaming and forming apparatus of type and method that is used for synthetic resin and reaches foamed molded product in the type of making thus, this technical scheme relates to the feed particles feeding mechanism, it is will comprise that by means of air stream the feed particles of thermoplasticity synthetic resin is transported to the die cavity of core and swaging die composition through tucker from head tank, is exactly the foam beads charging gear in fact.When this kind device is used for the supply of foam material, being easy to conglomeration at the discharging opening of hopper gets lodged near the discharging opening, cause blanking inhomogeneous, more disadvantageously, the foam beads mutual friction generation static conveying pipeline that comes out from fluid bed is easy to unite and then block conveying pipeline, this moment, the air outlet and the pressure between the conveying pipeline blocking portion of blower fan increased, the air that blower fan blows out will discharge from the feed opening of hopper, thereby fail in conveying pipeline, to set up certain pressure, foam beads is stifled more many more, thoroughly blocks at last.

Summary of the invention

The purpose of this utility model provides a kind of uniform feeding, the reliable foam beads charging gear of feeding.

The technical solution of the utility model is such: a kind of foam beads charging gear, the conveying pipeline that comprises hopper and connection hopper discharging opening, described conveying pipeline also connects the air outlet of air blast, be provided with a rotor between described hopper discharging opening and the conveying pipeline, the rotor circumference lateral wall is provided with at least three feeding blades, and the vertical end of described rotor connects clutch end.

Above-mentioned foam beads charging gear, described each blade is provided with the hairbrush that is used to scrape off the minority residual particles and has the air-isolation effect away from that side of rotor sidewall.

Above-mentioned foam beads charging gear, described feeding blade are three to eight.。

The utility model is provided with the rotor of band feeding blade by the discharging opening at hopper, make foam beads enter conveying pipeline quantitatively by feeding blade, the hairbrush of blade end can not only brush away residual small amount of foam particle simultaneously, and can combine the space that makes between the blade with the sidewall of hopper and keep apart, like this, air pressure in the conveying pipeline is in a metastable state, conveying pipeline is difficult for stopping up, and when situation appears uniting in foam beads, this pressure is enough to that the situation of preventing is broken up in this conglomeration further to be developed toward unfavorable direction, guarantee that feed bin and feeding process foam beads are evenly distributed, and then guarantee the packing of foam-formed product.

Description of drawings

Fig. 1 is the utility model embodiment schematic diagram;

Fig. 2 is the local enlarged diagram of Fig. 1 rotor;

The specific embodiment

Design philosophy of the present utility model is: at the feed opening of hopper the device of a dosing is set, this device can be isolated the space between each blade on the other hand with the parameter feeding of setting on the one hand, guarantees the stable of conveying pipeline pressure, prevents that putty from taking place.

With reference to figure 1, Fig. 2, embodiment provides a kind of foam beads charging gear, the conveying pipeline 2 that comprises hopper 1 and connection hopper 1 discharging opening, described conveying pipeline 2 also connects the air outlet of air blast 3, described hopper 1 discharging opening is provided with a rotor 4, be located on hopper 1 discharging opening by two rolling bearings near the rotor 4 axial two ends, rotor 4 is positioned at its periphery wall of hopper 1 discharging opening inside part and is provided with six feeding blades 41, each feeding blade 41 is provided with hairbrush 42 away from that side in rotor 4 axle center, described hairbrush 42 and feeding blade 41 are the same to be extended axially along rotor 4, described rotor 4 axial ends connect the reduction box output by belt pulley or chain, and the reduction box input is connected with motor output end.In the present embodiment, described feeding blade 41 is not defined as 6, can be that 3 or 8 or other number can both realize the purpose of this utility model.

The utility model is used for the production equipment of foam-formed product, rotor 4 rotates with constant speed under the drive of motor, epitrochanterian feeding blade 41 is delivered to conveying pipeline 2 to foam beads from hopper 1 quantitatively, under the effect of air blast 3, be sent to feed bin or next process then, and stop up in the chamber that the hairbrush 42 of feeding blade 41 ends can be isolated between the feeding blade 41, the space at place is isolated between the space at place between the feeding blade on the conveying pipeline 2 41 and hopper 1 blanking part feeding blade 41 like this comes, the pressure of conveying pipeline 2 is in a metastable level, thereby prevents that conveying pipeline 2 from stopping up.

Claims

1, a kind of foam beads charging gear, the conveying pipeline that comprises hopper and connection hopper discharging opening, described conveying pipeline also connects the air outlet of air blast, it is characterized in that being provided with a rotor between described hopper discharging opening and the conveying pipeline, the rotor circumference lateral wall is provided with at least three feeding blades, and the vertical end of described rotor connects clutch end.

2, foam beads charging gear as claimed in claim 1 is characterized in that described each blade is provided with the hairbrush that is used to scrape off the minority residual particles and has the air-isolation effect away from that side of rotor sidewall.
